SI4699-A10-AMR

Overview

The SI4699-A10-AMR is a high-performance dual digital radio coprocessor designed for automotive applications. It supports AM, FM, HD Radio, DAB, and DAB+ reception within frequency ranges of 520 kHz to 1.71 MHz and 76 MHz to 108 MHz. The device operates on a 1.8 V supply voltage and features I2C and SPI interfaces. It is housed in an LGA-72 package measuring 10x10 mm and is rated for temperatures between -40°C and +125°C.

Feature Summary

• Dual-channel architecture supporting simultaneous reception of multiple broadcast standards including HD Radio and DAB/DAB+.
• Automotive-grade reliability certified under AEC-Q100 standards for harsh environment operation.
• Integrated digital signal processing for AM, FM, and satellite radio formats without external baseband components.

Applications

• Automotive infotainment systems requiring multi-band radio reception
• Vehicle navigation units with integrated audio broadcasting capabilities
• Advanced driver assistance system (ADAS) audio interfaces

Procurement Notes

Verify the specific suffix 'AMR' confirms the automotive grade and LGA-72 package variant. Confirm current production status as active or obsolescence notices. Ensure compatibility with existing board layouts for the 10x10 mm footprint. Validate temperature ratings against final assembly environmental requirements.

Selection Notes

Select this component when dual-receiver functionality is required for redundant or simultaneous band tuning in automotive environments. Compare against single-receiver models like SI4690 if only one standard is needed. Consider power consumption profiles relative to vehicle battery management systems during standby modes.

Part Context

This part belongs to Skyworks' Si46xx series of digital radio receivers. It complements other variants like SI4694 by offering specialized automotive certification. The series integrates RF front-end control and digital demodulation into a single compact solution.

Replacement Considerations

Check for direct pin-compatible substitutes within the SI4699 family. Verify if older revisions require firmware updates for equivalent performance.

FAQ

Does the SI4699-A10-AMR support both HD Radio and DAB simultaneously?

Yes, the dual-receiver architecture allows for independent tuning channels that can process different standards concurrently.

What is the operating voltage range for this coprocessor?

The device is designed to operate at a nominal 1.8 V supply voltage.
